How dare anybody wear clothing from outside their own culture. People must ONLY dress according to their ethnicity. Fun, sharing, and wearing anything 'foreign' is prohibited. Every time a white Brit wears a sombrero, a Mexican cries. Even if a Mexican sold it to you on vacation, you must not wear it. Got it?
That goes for Cowboys, too. Cattle ranchers and gunslingers are a culture, not a costume! A Toga, Zoro outfit, or lederhosen? FORGET ABOUT IT, BIGOT!
*Rules only apply if you are a white. If you're Chinese and want to wear a Geisha outfit, or Nigerian and want to dress like a Maasai, have at it, because we won't be able to tell the difference.
